Check Digit Verification of cas no

The CAS Registry Mumber 556-34-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 556-34:
(5*5)+(4*5)+(3*6)+(2*3)+(1*4)=73
73 % 10 = 3
So 556-34-3 is a valid CAS Registry Number.
